Tympanic membrane perforation is one of the causes of hearing loss and can causerecurrent middle ear infections. Myringoplasty is a procedure for reconstruction of the tympanicmembrane perforation by using a ring in the ear with a complete hearing bone chain, goodmotion, and no pathological tissue in the middle ear. Myringoplasty aims to improve hearingfunction and prevent recurrent infections of the middle ear and inner ear. This study aimed tofind out the hearing characteristics of patients after myringoplasty based on an image of pure tone audiometry in the THT-KL Poli RSHS Bandung period January - December 2016. This is aretrospective descriptive study of patients undergoing myringoplasty. There were 285 new casesof tympanic membrane perforation with an age range of 15-55 years; 153 men (53.7%), 132women (46.3%), 109 (50.27%) patients had an increase in the hearing threshold of 10.1 dB - 20dB, reaching a normal hearing threshold of 249 (87, 4%) patients, and closure of perforationwere 254 (89.1%) patients. In a conclusion, there was a good hearing improvement aftermyringoplasty on tympanic membrane perforation without other abnormalities. Keywords: Myringoplasty, perforation of the tympanic membrane, increased hearing threshold.

Operative Findings

Introduction             Chronic otitis media (COM) is a most common and prevalent disease of the middle ear. COM has been defined as a longstanding inflammatory condition of middle ear and mastoid, associated with perforation of the tympanic membrane. Tympanoplasties are common surgeries performed for chronic otitis media in inactive mucosal type. Any otological surgery may involve a menace/ hazard of hearing loss post operatively.             In this study, an attempt was made to correlate, size of tympanic membrane perforation, pure tone audiometry and intra-operative findings in tympanoplasties, results were analysed and conclusion drawn. Materials and Methods Forty patients attending ENT OPD with chronic otitis media (COM), inactive mucosal type, with conductive hearing loss undergoing tympanoplasties who were willing to participate in the study were selected.  Ear was examined pre-operatively to assess the size of perforation and then, pure tone audiometry (PTA) was done to assess the type of hearing loss and its severity. During tympanoplasty, middle ear was inspected for ossicular status and any other pathology was noted. Later, the size of tympanic membrane perforation, pure tone audiometry and intra operative findings were correlated with each other and analysed. Result  In small and medium sized perforation, PTA and intraoperative findings correlated with each other. Whereas, in large and subtotal perforation, there was no correlation. Conclusion             In small and medium sized perforation, middle ear inspection may not be necessary. Whereas, in large and subtotal perforation it is necessary.

<p class="abstract"><strong>Background:</strong> Tympanoplasty is a surgical procedure for closing the tympanic membrane perforation and reconstructing the tympanic membrane and hearing, commonly after trauma and chronic otitis media. The aim of the study was to compare the clinical and audiological outcomes of tympanoplasty with or without anterior tucking.</p><p class="abstract"><strong>Methods:</strong> In this prospective study, 50 patients with chronic otitis media (COM) were divided into two groups. Group 1 underwent type 1 tympanoplasty with anterior tucking method, and group 2 underwent type 1 tympanoplasty without anterior tucking. The result was measured on graft uptake and hearing outcome at 6 months postoperatively by performing pure tone audiometry.  </p><p class="abstract"><strong>Results:</strong> The hearing improvement was almost the same in both the groups. Graft uptake was good in type 1 tympanoplasty with tucking (96%) when compared to without tucking tympanoplasty (92%). Complications like residual perforation were seen in both groups equally. Anterior marginal blunting was noted (8%) in type 1 tympanoplasty with tucking.</p><p class="abstract"><strong>Conclusions:</strong> The hearing improvement of type-1 tympanoplasty with anterior tucking and without anterior tucking is the same. Type-1 tympanoplasty with anterior tucking has a better graft acceptance. The only disadvantage of type-1 tympanoplasty with anterior tucking is anterior marginal blunting.</p>

Problem Gelfoam has been used for decades in otologic surgery to support grafts and prostheses despite causing fibrosis and adhesions. More biocompatible packing materials could avoid these complications. This study compares Gelfoam with an injectable esterified hyaluronic acid, Merogel, as middle ear packing material after mucosal trauma. Methods A randomized, blinded, controlled study was performed in 17 juvenile guinea pigs. Middle ear surgery with mucosal trauma was performed and middle ears were packed with Merogel or Gelfoam; unpacked contralateral ears were used as controls. Auditory brainstem response (ABR) thresholds were measured in 4 frequencies pre-operatively, and repeated at 1, 2, and 6 weeks postoperatively. Gross analysis measured inflammatory reaction in each group. Statistical analysis was performed using ANOVA followed by post-hoc analysis for ABR thresholds and packing remaining at 6 weeks. Non-prametric tests were used for presence of mucosal inflammation, effusion and tympanic membrane perforation. Results ABR threshold changes from baseline were minor and comparable between the Merogel group and the control group. Threshold change was higher in the Gelfoam group. This difference was seen in each frequency tested at each time interval (all p<0.05). Gross analysis showed 1) Mucosal inflammation higher in the Gelfoam group (p<0.05), 2) Effusions were higher in the Gelfoam group but the difference was not significant (p=0.07), 3) Tympanic membrane perforation was equally rare between groups (p>0.05), 4) Unabsorbed packing was higher in the Gelfoam group (p<0.05); little Merogel was detectable at time of sacrifice. Conclusion Middle ear healing after surgery occurred similarly in the control group and the Merogel group. In contrast, the Gelfoam group demonstrated greater perturbation of hearing and a greater inflammatory reaction. Significance These results support Merogel as an alternative to Gelfoam in middle ear packing after otologic surgery. Support Research grant from Medtronic ENT.

Abstract Introduction The effects of tympanic membrane perforations on middle ear sound transmission are not well characterized, largely because ears with perforations typically have additional pathological changes. It has been established that the larger the perforation, the greater is the hearing loss (HL). Aim This study aimed to correlate the location and size of tympanic membrane perforation and middle ear air space volume with the magnitude of HL in patients with tubotympanic or inactive mucosal type of chronic otitis media (COM). Materials and Methods A prospective clinical study of patients with tympanic membrane perforations due to COM and without any other ear disease and who attended the Otolaryngology services at our institute between July 2010 and December 2011 was conducted. A total of 300 ears were evaluated by performing otoendoscopy, followed by photo documentation and audiological investigations (pure-tone audiometry and tympanometry). Tympanic membrane perforations were categorized based on their size and location, and the mean air-bone (AB) gap between the various types of perforations was compared and statistically analyzed with significance level of p < 0.05. Results Out of 300 ears, maximum number of ears (n = 124, 41.3%) had large-sized perforations (> 30 mm2) that had a maximum mean AB gap of 26.43 dB, and minimum number of ears (n = 60, 20%) had small-sized perforations (0–9 mm2) that had minimum mean AB gap of 9.12 dB. The remaining were medium-sized perforations that had mean AB gap of 16.13 dB. Depending on the location, maximum were central perforations (n = 198, 66%) and minimum were anterosuperior (AS) perforations (n = 9, 3%). Based on the middle ear volume on tympanometry, maximum ears were of low-volume group (n = 246, 92%) that had larger mean AB gap of 19.96 dB HL when compared with the high-volume group (n = 24, 8%) with 11.80 dB HL. AB gap was maximum at lower frequencies and decreased with increase in frequencies except at 4,000 Hz, that is, 56.9 dB HL at 250 Hz, 42.6 at 500 Hz, 41.5 at 1,000 Hz, 32.4 at 2,000 Hz, and 49.5 at 4,000 Hz. Conclusion HL increases as the area of tympanic membrane perforation increases. There is an inverse relationship between HL and middle ear air space volume. Comparing the small-sized perforations at different sites with the middle ear volume being low, it was found that posterosuperior (PS) perforations had 4 to 7 dB greater HL than AS and anteroinferior (AI). However, the relationship was statistically insignificant. The phase cancellation effect of round window causing greater HL in posteroinferior (PI) perforations does not exist in small- and medium-sized perforations. HL is greater at lower frequencies and less at higher frequencies.

Ear Drops

Ear drops containing neomycin only rarely cause ototoxicity. The authors report on three patients with a tympanic membrane perforation who developed severe ototoxicity after use of eardrops containing 0.35 per cent neomycin. Mitochondrial DNA analysis revealed that there was no A1555G point mutation in these patients. This finding indicates that application of low concentration neomycin to the middle ear can cause severe inner ear damage even in humans who are not hyper-susceptible to aminoglycosides.
